| 摘要： | The Rock Island Engineer District and the U.S. Geological Survey, in partnership with others, released a report on June 22 titled "Ecological Status and Trends of the Upper Mississippi and Illinois Rivers." The report is prepared by the Upper Mississippi River Restoration program, a partnership of federal and state agencies, non-governmental organizations and individuals working together to support Upper Mississippi River System ecosystem rehabilitation, research and monitoring. Although previous status and trends reports were released in 1998 and 2008, the latest one is based on 25 years of data. The picture it offers of the rivers' ecological health is mixed but encouraging. |
